SMTP Test/Usage Via Telnet

November 2011 · 1 minute read

A telnet client is a handy testing tool for testing connectivity between servers. Today I needed to test an SMTP server connection from a linux environment so I wrote the following script. You could use the same technique manually to do the same thing as long as your have access to a telnet client.

Usage

The script takes three parameters: the smtp server url, the sender address and the recipient address.
